1974 Mercury 20hp prop

[Jesse4533]

Hey guys I am looking for a replacement prop for my 1974 Mercury 200 serial number 3670672. I am pretty positive it's got the original on it now and was wondering what the original size and pitch is. I have the engine on a 14' sea nymph and it's a tiller motor. I am looking for one that would work for that configuration if you all have any recommendations! Thanks for all your help!
